CLEANING COMPOSITION FOR TYPE AND THE LIKE.

Io Drawing.

This invention relates to improvements in cleaning compositions for type and the like, and more particularly a composition for cleaning typewriter and other kinds of type, 'ewelry," and any other article or material aving a surface of small indentations or projections and which heretofore have been cleaned by means of a brush, or with a liquid preparation containing a cleaning agent or solvent.

The object of the inventionis to provide a cleaning preparation which will bring about a new method of removing dirt and foreign matter from surfaces such as type, namely, by adhesion rather than by rubbing or wiping with a cloth saturated with a solvent.

A further object of the invention is to provide a cleaning composition having somewhat the consistency of kneaded rubber,

but differing essentially therefrom in that the cleaning is accomplished by pressing the material against the surface or face of the type to be cleaned, with the result that a clear impression is made in the contacting surface of the composition, and when removed brings with it all the dirt, dried ink or foreign matter that is lodged in the small indentations or crevices in the surface. Such a composition is clean and stainless, depending on its adhesive roperties to accomplish the intended resu ts, and hence is readily distinguished from erasive materials which depend on rubbing or friction. Moreover, the com osition' is so compounded as to prevent its sticking to the surface being cleaned, but simply to remove and absorb the dirt, leaving the surface bright and clean.

In disclosing the nature of the compound it is to be borne in mind that as in other chemically and ph sically incorporated mixtures, each ingre 'ent may have numerous substitutes which differ slightly: in their chemical and physical properties but produce the same general type of reaction or product when brought together.

For this reason I prefer at the outset to discuss the character of the composition in terms of classes of ingredients rather than species, and then to give an example of a composition that has been wholly satisfactory and perhaps preferable as a com mercial product.

Following this procedure, therefore, the base-or basis of this composition is the re- 'sulting product formed from the incorpora- Application filed December 2, 1925. Serial so. vans.

tion. with an inherent adhesive substance, such as crude rubber, of certain water insoluble soaps such as palmitates, oleates steal-ates, or resinates of the various metal bases commonly included among the insoluble soaps, to-wit, aluminum, magnesium, calcium, etc. Included in the class with crude rubber as an adhesive are its related compounds, such as balata or gutta percha gums.

Incorporated with the adhesive and insoluble soap are certain oils calculated to produce variousdegrees of softness and adhesiveness, namely, mineral or animal oils or non-oxidizing vegetable oils as the softener, and rosin oil to produce the desired property of stickiness or tackiness. To this product is added various ingredients which serve as a filler to give body and reduce or temper the stickiness of the material. Such ingredients are talc, soapstone, mica, magnesium carbonate, zinc oxide, zinc carbonate, lithopone or calcium carbonate. Practical] many oxi es can be used, together with various pigments to give color or weight to the product. The consistency of the product is manifestly determined by the proportion of the several ingredients present. For general use it has a soft and pliable consistency, and can readily .be worked or kneaded between the fingers. It follows also that its consistency may be varied to suit different needs. 1

Referring now to a concrete example of a composition containing specific ingredients Selected from several classes or groups of substances already mentioned, I find as a suitable adhesive crude rubber gum f as the preferred insoluble soaps I have selected aluminum and calcium palmitates; as a suitable oil for solvent and softening purposes, I find that any mineral oil, such as light, medium or heavy paraflineoils, and common,- ly known as lubricating oils, are satisfactory; and ass, substance to increase thetackiness or adhesiveness, I have selected rosin oil asthe most suitable oil to use, but other oils hailing like properties might equally well be se I As to the ingredients added to give the material body and stiffness, and to reduce the stickiness to just the right amount to produce the proper adhesiveness, I have ound that many substances are suitable for all carbonates, silicates and the purpose, and therefore I have little or no preference between the carbonates of various metals, such as magnesium, zinc and calcium and their oxides, and such silicates as talc, soapstone or mica, although I refer to use a combination of one or more 0 these carbonates and silicates, as the filling substance. As a final ingredient of the composition is added certain pi 'ments to produce the proper colors. anifestly the coloring of the composition does not affect its physical properties.

'lhe preparation of the composition is a matter of mixing the several ingredients in the required proportions and. by suitable means for the purpose. The rubber gum is preferably softened by running the same through rollers, whereupon the soap, oils, and inert materials, together with the desired pigments or colors are then added in the amounts hereinafter prescribed, and within limits governed by the character of the product desired and the use to which it is to be put.

Having described the constituents of the composition (possible as well preferred), 1 will first give the variable proportions of the basic ingredients as they would be used, such proportions servingas a general guide to ma for those desiring e use of the invention:

For rent.

Rubber gum from 5 to 20 Insoluble soap from 15 to 40 Filler "from 40 to Oil from 15 to 20 Rosin oil "from 8 to 15 In addition to the foregoing I will also give a formula which I have found to be workable for general use:

Per cent. River Para gum 10 Calcium and /or aluminum palmitates 40 Calcium and /or magnesium carbonates-) 20 Mineral oil 20 Rosin oil- 10 Slight variations may be made from these percentages without materially afiecting the character and properties of the compostion. No particular amount of pigment is speci fied, since this may be varied considerably with the color desired, in fact, the pigment may be omitted entirely.

be material when properly mixed is of sutlicient body to clear] take very sharpl defined impressions.- or instance, wit typewriter type, the impressions are an exact reproduction of the type. The adhesiveness of the material is just suflicient to withdraw from the type or projection all dirt and foreign materials without leaving any of the material on the type. By kneading the sition for the material in the fingers as it is used, the dirt is distributed throughout the mass, and as a result can be used many times before it becomes so saturated as to be unusable.

Among the advantages of the use of such a composition is its cleanliness of operation, as compared with the common practice of using a brush and alcohol, gasoline or other solvent, with the attendant possibility of sputtering and soiling the hands and clothing of the operator. Moreover, it obviates the usual trouble caused in cleaning typewriters,that of rubbing the type sideways with a brush which tends to bend them out of alignment. With the present cleaner, the material is pressed firmly against the t pe. which in turn are held firmly against. t ieir supports, and thus are always in the proper alignment.

Although I have disclosed a preferred em bodiment of the invention, it is to be understood that I do not wish to be limited to any specific materials to be cleaned or to any specific ingredients except in so far as heretofore suggested and more specifically pointed out in the appended claims.
